Remove Audio Metadata
Strip ID3 tags and other embedded metadata from an audio file before sharing it, without re-encoding the audio itself for MP3 files.
How it works
- 1
Drop an audio file onto the upload area and click Remove metadata.
- 2
For MP3 files, ID3 tags at the start and end of the file are removed without touching the audio frames — no re-encoding, no quality change.
- 3
For other formats, the file is re-muxed through the browser's audio engine to drop embedded metadata, then returned as a clean file.
Questions
Is the audio quality affected?
For MP3: no. ID3v2 tags sit in identifiable blocks before the audio frames, and ID3v1 sits in the final 128 bytes. Both are cut out without decoding a single audio frame, so quality is unchanged. For WAV, M4A, OGG and other formats, the file is re-muxed through the browser's codec, which may introduce a small quality change for lossy formats.
What metadata does this remove?
For MP3 it removes all ID3v2 tags (title, artist, album, artwork, and any other embedded frames) and the ID3v1 block if one is present. For other formats, it removes whatever metadata the container's remux step discards — typically all standard tag fields.
Why does my WAV or M4A file get re-encoded?
Unlike MP3, these formats do not store tags in easily separable byte ranges. Removing them requires reading and rewriting the container, which the browser's audio engine handles. The audio content is preserved as faithfully as the codec allows.
Is my file uploaded anywhere?
No. All processing happens in your browser. The file never leaves your device.
